5、onsiderations for Airborne Implementation of Enhanced Synthetic Vision Systems RATIONALE The use of enhanced visual scene content as both a tool to increase situation awareness and as a sole flight guidance display has increased and will continue to increase. Correct implementation of these types of
6、 displays is essential and critical to safe operation. SAE G-10 Aerospace Behavior Engineering Technology (ABET) Committee, specifically the Enhanced Vision/Synthetic Vision (EV/SV) Subcommittee, has been tasked to provide implementation document guidance associated with the human interface consider
7、ations in the design, development and implementation of enhanced synthetic vision systems. FOREWORD This document identifies the recommended human engineering best practices in the design and implementation of Enhanced Synthetic Vision Systems (ESVS). It draws from ARD50019A, Human Engineering Issue
8、s for Enhanced Vision Systems and other applicable ESVS data including developmental flight evaluations and fielded data. This document is intended to provide a central source for recommending human engineering applications concerning ESVS and as an aid for development, design and implementation. DE
9、FINITION An enhanced synthetic vision system (ESVS) generates and displays visual imagery based upon real-time sensor data, fused (integrated into), not “overlayed on” as in a Combined Vision System (CVS) implementation, with a data-based computer-generated image representing the out-of-the-cockpit
10、view of terrain and selected scene data. The sensor(s) is/are designed to provide useable imagery in degraded environmental visual conditions that enhances the capability of unaided human vision, while the computer generated scene is unaffected by environmental conditions.

NOTES 30 SAE ARP5677 Page 4 of 32 1. SCOPE 1.1 SCOPE The scope of this document is limite
19、d to Enhanced Synthetic Vision Systems ESVS human factors considerations and requirements in comprehension, interpretation and application of imagery and integrated symbology in Enhanced (sensor) and Synthetic (database) Vision Systems in aircraft. Any overlap into logic problems or hardware/softwar
20、e design should be considered to be incidental to the human factors issues. Where the performance characteristics of specific technologies are relevant they will be identified, and where performance criteria are relevant to specific intended functions/use they will be identified. From a regulatory v
21、iew, intended function (Guidance or Information/Situation Awareness support) has a tremendous effect upon the design of an ESV System. However from a Human Engineering standpoint, the information on a display must be discernible and comprehensible to the human operator in both cases and differences
22、may be primarily in information content (required to support a specific task). This document attempts to be independent of candidate technologies and concentrate on human interface criteria. Consideration of NVG use in a cockpit equipped with ESVS is beyond the scope of this document, but it should
23、be noted that there will be significant integration/interaction issues such as black level limits and use of DTED data simultaneous with NVS. This document does not include consideration of detection and/or display of air targets or integration of systems such as TCAS. 1.2 Purpose This document is a
24、 compilation of human factors recommended practices in the design of ESVS. It may be updated to reflect research and development results and as the technology improves and applications expand, the coverage of the document will be expanded. 2.

44、OCENTRIC: Scene-based frame of reference particularly with respect to the objects spatial location; an observer-independent (possibly earth-fixed) frame of reference.

45、orming as a recognizable whole. Federated avionics architecture consists of “stand alone“ sub-systems and their integration into an overall system is carried out by the crew. Integrated modular avionics architecture relies on the use of a limited range of standard modules which are packaged in a sta
46、ndardized modular format and installed is a small number of common racks. CLUTTER: Clutter is an attribute of poorly organized and crowded displays. A cluttered display is one which uses an excessive number and/or variety of symbols, colors, or small spatial relationships. This causes increased proc
47、essing time for display interpretation. It generally results in reduced display legibility, and/or in increases in the time needed to locate and interpret information on the display. COMBINED VISION SYSTEM (CVS): A displayed image combining a selected database image (e.g., airport approach data, syn
48、thetic image data) overlayed with active sensor image data. COMMAND INFORMATION: Information that directs the pilot to follow a course of action in a specific situation (e.g., Flight Director or TCAS RA - resolution advisory). COMMAND REFERENCE FRAME: A symbol, appropriately colored, indicating the
49、position within which the pilot should place the flight path marker to affect the desired flight performance response. CONFORMAL INFORMATION: Information which correctly overlays the image of the real world, irrespective of the pilots viewing position. Conformal means having a 1:1 angular and scalar relationship. For displays the field of regard is the same as the field of view. COPLANAR DISPLAYS: Devices whose display surfaces lie in the
